I missed your post, glad I noticed it now, thanks.
So Quick Controls only follows a single midi channel assigned from the track, and it will not follow the Expression Map midi channel assignment… which is what is certainly happening here. That, to me, is incorrect midi behavior. If you have Expression Map controlling your midi channels to access different instruments, and your keyboard controller and hardware controller(s) are following that, logically you would want your Quick Controls to follow that too, yes? To me it is the only correct behavior. Am I missing something?
